Chemical Imaging of the Spatial Distribution and Interactions of Tannin Dispersal in Bioplastic Systems

IR chemical imaging has been used to characterise the dispersion of condensed tannin additives in a biodegradable plastic, poly(butylene succinate). By mapping key FTIR absorptions, acetylated tannin was found to remain in discrete aggregates, though the outer of these particles contained a mixed phase with PBS. In particles >100 μm, PBS does not appear to ingress the tannin core, only wetting the outer region. Analysis of a second tannin derivative indicated that there was a more uniform dispersion of the additive in the PBS matrix.
